Freebie IBM XML Registry Tool and Utility Services

IBM apparently wants XML standards so that XML becomes more of a standard. Last week, the company put forth a new free extensible XML resource on its alphaWorks site that it says lets developers store, search, and manage XML-based applications. Using the tool, IBM says developers can manage their XML schemas (DTD, XSD), stylesheets (XSL), and documents (WSDL) with the new XML Registry/Repository (XRR) data management system by downloading XRR from the alphaWorks site. The tool lets end users search or browse for an XML document or schema, then insert the document into their application. XRR lets IBM's DB2 Database store and search XML documents by content, including tasks like registration, searches by metadata, classification, and association. XRR is an implementation of the OASIS XML Registry Working Draft Specification 1.1. The alphaWorks site is also offering free utilities and a new subscription model for online applications. From what I read, alphaWorks utilities are a prototype of a network-based computing service model that is supposed to let customers subscribe to services purchased on a measured unit such as time, capacity or throughput. IBM's first Utility Service will appear as a trial download on alphaWorks, and is a Publish/Subscribe Message Brokering (PSMB) system. PSMB middleware supports the routing of information via streaming events from information providers to information consumers. Remember that alphaWorks is a setup where you download apps and such before they reach prime time. The theory behind it seems to be that by putting stuff out there, it will get batted about by developers, hence getting the finished products to market sooner. Kind of a "Play Before You Pay" model, but with your input, the end products are (theoretically) more likely to contain features that you want to see. I'm sure those in the know will clue me in.
